[…] When Infinio supports Hyper-V, it looks like I’ll need to compare us to CSV Cache as well. […]

In reply to Ingmar Verheij. CBRC (Now called VSA) was before the Virsto aquisition

To follow up Ingmar’s point there.. Atlantis Computing have a software solution that works with ESX, Hyper-V and Xenserver to improve not only the read IOPS, but the write IOPS as well.

Read performance very useful,say, in a boot situation. But, how quickly the VM boots is going to impact the user for a point in time. Having write optimisation will ensure a fast, consistent experience for their entire session. I wouldn’t consider Atlantis ILIO only as a replacement to CRBC – use them together and you’ve a very powerful storage optimisation solution and enhancement for your VDI environment.

If you’re off to E2E in Rome – a virtualisation conference I can thoroughly recommend – by all means drop into our session 😉

VMware released version 5 (including CBRC) of VMware vSphere On August 27, 2012, the acquisition of Virsto was on Feb. 11, 2013.

I could be mistaking, but isn’t VMware CRBC the result of the Virsto acquisition?

Hi Kees
Good comparison. As Server 2012 R2 introduces automatic storage tiering, I believe the Microsoft solution is the most complete one from a single vendors perspective. You can now also leverage up to 80% of your SOFS nodes RAM for CSV Cache and use SSD based and clustered storage spaces. VMware IMHO has too much focus on VDI in their enhanced feature stack. Traditional high peak server workloads have demands for those improvments too.

Cheers

Hi Kees,

Good to see that both Microsoft and VMware are starting to mitigate the most common problem when virtualising interactive desktop systems: IOPS. What’s interesting is that while VMware CRBC is only available for VMWare View, not Citrix XenDesktop. Hyper-V CSV Cache is supported for XenDesktop but VMware View isn’t supported on Hyper-V making them mutually exclusive.

Maybe I’m stating the obvious here, but there’s a software alternative that’s not only supported on both VMware AND Hyper-V (allowing XenDesktop customers to run on the VMware hypervisor) but also optimises write IOPS. Sure nonpersistent machines have less write IOPS then persistent machines, but Windows simply keeps writing (temporary and useless) blocks of data that are a waste of your expensive SAN! That same software solution can leverage both RAM and local disks (SSD / FusionIO) – Like XenServer Intellicache – making it more versatile.

It will be interesting to see if this is a reason for Citrix XenDesktop customers to take (another) look at Hyper-V, or the software solution.

Cheers,
Ingmar
